5 True/False Questions

  1. dehydration reactionA reaction in which two molecules become covalently bonded to each other through the loss of a small molecule, usually water; also called dehydration reaction

          

  2. amino acida long carbon chain carboxylic acid. fatty acids vary in length and in the number and location of double bonds; three fatty acids linked to a glycerol molecule form fat

          

  3. RNAA double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins

          

  4. geneA type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses
